FireStudio Family - Why is the Universal Control crashing when I launch it?

There is a known issue that prevents the FireStudio family driver from properly overwriting earlier versions of its files on some systems. This can create a driver conflict that prevents the control panel from working properly. A complete manual uninstall of the driver can resolve this issue.

Please note: Your FireStudio family interface should have a solid blue sync light and will be recognized within the AudioMIDI setup utility as an available audio and MIDI device if a driver conflict is the cause of the errors listed above. This FAQ will guide you through the complete uninstall process and well as downloading the latest driver from the PreSonus website and installing in on your Mac.

Removing FireStudio family Driver Files

1. Disconnect your FireStudio Family interface

2. Double click on MacHD to launch a new finder window. The following list includes every possible file that may have been installed on your Mac, depending on which driver versions you have installed. If you do not see one of these files, do not be alarmed. The files are listed by location tree. For example, to locate the MacHD/Library/Preferences/PaeFireStudio.startup file, you will double click on MacHD and Open the Library folder. In the Library folder, you will open the Preferences folder where you will find the PaeFireStudio.startup file. This is the file you will move to the Trash.

Delete the following from your computer (note some files will require that you type in your administrative password):

15. Download the driver for you FireStudio family product from the PreSonus website. The zipped file will be automatically extracted and stored in the Downloads folder on your computer unless you have manually changed this preference in Safari.
